Detection clamp of large gear

Abstract

The invention relates to a detection clamp of a large gear, which is arranged on a detection platform of a gear detector. The detection clamp comprises an adjusting base and an adjustable equal-height block, wherein the adjustable equal-height block is arranged on the adjusting base; the adjusting base includes a base, an upper-layer adjusting platform and a lower-layer adjusting platform, wherein adjusting handles are arranged in the middles of both sides of the base and the lower-layer adjusting platform in pairs, and the tips of the adjusting handles respectively abut against the side surfaces of the upper-layer adjusting platform; the adjusting platforms are positioned by being matched with positioning blocks through sliding strips arranged on adjacent surfaces and can oppositely slidably move; and a supporting platform of the adjustable equal-height block is matched and connected with a block seat through a height adjustment screw. The invention can conveniently adjust an axis ofthe gear to be coincided with the axis of the detection platform by utilizing a cross sliding guide rail and conveniently adjust the end surface of the gear to be parallel to the detection platform through the adjustable equal-height block, meets the standard requirements for precise positioning, greatly enhances the detection efficiency without impact and can not damage the gear and an apparatus.

Description

technical field [0001] The invention relates to the field of gear detection equipment, in particular to a large gear detection jig. Background technique [0002] Gear tooth accuracy such as tooth shape, tooth direction, and radial runout are important indicators in gear processing and production, and universal gear detectors are generally used for testing. When testing, the gear needs to be correctly installed on the testing platform, which needs to meet two benchmark requirements: one is that the axis of the gear should coincide with the axis of the testing platform, and the other is that the end face of the gear should be parallel to the testing platform. For small-sized gears, the positioning of the axis and end faces generally depends on the mandrel, but for large-sized gears, because the weight is heavy and the inner hole is large, the mandrel and the top cannot bear the weight, so it is generally used at present. The gear is placed on the equal height block of the det...

Problems solved by technology

[0003] In view of the disadvantages of the above-mentioned existing large gear detection method of using a copper rod to knock the gear, the applicant provides a large gear detection fixture with a simple structure and convenient adjustment, which has the disadvantages of low efficiency, damage to the gear and the detector, and the like. It can be easily adjusted to meet the benchmark requirements, improve the detection efficiency, and will not cause damage to gears and instruments
